The foam block being glued to the scoop, it's time to make the cut. Here, the begining.



And now the cut is finished. The picture shows the the foam doens not extend completely to the airbox. This is not really a problem.
A run into trouble when I began sanding the foam as it is very fragile. I wasn't carefull enough and am not satisfied with the result. So I glued another foam block and am back to square one.
